30 is not too old, however you have to appreciate that you are not starting young.
Most young kids are overly infusiastic, they lift alot of weights with bad technique & train whilst injured. All this they pay for later in life with various aches and pains.
Assuming you have taken care of yourself you should be able to get a few good years in after a few years of training. Listen to your body and do not over train etc.
